Ophthalmologic composition and ophthalmologic lens
The invention relates to an ophthalmologic composition including a dye of the general formula I in which R 1 =substituted or unsubstituted hydrocarbon radical, R 2 =substituted or unsubstituted hydrocarbon radical with at least one polymerizable double bond, R 3 ═H or substituted or unsubstituted hydrocarbon radical, R 4 ═H, electron-withdrawing substituent or substituted or unsubstituted hydrocarbon radical and X═O, S, NH or NR 5 , wherein R 5 is a substituted and/or unsubstituted hydrocarbon radical. Moreover, the invention relates to another ophthalmologic composition and an ophthalmologic lens.
